Best answer
Correct option is (d) Radiation

For explanation I would say: Radiation is the fastest mode of transfer of heat, because radiation travels at the speed of light, which is very quick. The slowest mode of transfer of heat is conduction because it takes place from particle to particle. The fastest is radiation at the speed of light 3,00,000 km in one second.
